How to find If array contains two or more objects

Question

I'm attempting to implement the containsObject but with two or more parameters, is this possible?

Currently I've got:

and apparently there's too many arguments. I've delved through Apple's docs but I'm yet to find anything. Any suggestions?

if ([ myArray containsObject:@"1", @"2"]){
    NSLog(@"if");
} else if([ myArray containsObject:@"1", @"2",@"3",@"4"]) {
   NSLog(@"else if");
}else if([ myArray containsObject:@"1", @"2",@"3"]) {
   NSLog(@"else");
}

myArray:-

myArray is (
    1,
    2,
    3,
    4
)

you can check subsets of array

 NSArray *arry1= [NSArray arrayWithObjects:@"1",@"2",@"3",@"4", nil];
        NSArray *arry2= [NSArray arrayWithObjects:@"1",@"2", nil];

        NSSet *set1 = [NSSet setWithArray:arry1];
        NSSet *set2 = [NSSet setWithArray:arry2];

        if ([set2 isSubsetOfSet:set1])
        {
            NSLog(@"array1 contains all elements of array 2");
        }else{
            NSLog(@"array1 does not contains all elements of array 2");
        }
